Subject: drm/stm: check pitch and size calculations even if !CONFIG_MMU
Git-commit: 879659bb87a87a7a23b190e211d33bdd6763c746
Patch-mainline: v4.17-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

In all cases we have to check pitch and size calculations to speed up
data transfer.

Fixes: 21f815bf773c ("drm/stm: drv: Improve data transfers")
